Looking at the number of governments around the world who are trying to restrict their citizens from trading bitcoin in their countries, I believe it will still take a very long time for bitcoin to stand a chance to become the reserve currency of the world. In my opinion, I think the possibility of bitcoin to become the reserve currency of the world is extremely low.
Yes. There's still opposition from world governments into recognizing Bitcoin as a legal medium of exchange for people to use in their daily lives. While Bitcoin lives on the Internet, not everyone is permitted to gain access to it, if the government restricts it. For Bitcoin to achieve the status of a reserve currency of the world, it needs to be accepted as a legal currency in every country worldwide. Due to Bitcoin's decentralization, it's threating government's current economic system, which explains why some countries have devised laws against it. However, if Bitcoin becomes centralized, then it would gather the likes of banks and governments worldwide.
Despite this, I believe that there's no reason to worry about this, since Bitcoin will always serve as an alternative currency to Fiat. Without a doubt, a centralized currency will become the reserve currency of the world. However, it's a matter of time before the US Dollar remains as such, or another currency would take its place. For the meantime, Bitcoin could be the reserve currency of all the cryptocurrencies on the market today. Just my thoughts
